6 Set the Communication Analyzer to output a -47 dBm RF signal modulated with a 1 kHz tone at
60% of full deviation on the tuning frequency. The tuning frequency is the value displayed on the
Tuner GUI under the heading of "Frequency Points".
NOTICE:
The Tuner aligns this parameter in a 12.5 kHz channel spacing, so 60% is 1.5 kHz of
deviation. If the CPS is set for 25 kHz operation, the repeater automatically scales the
deviation by a factor of two when it is outside the Tuner application.
Programmed TPL and DPL squelch requirements are automatically disabled for the
tuning frequency while in the Tuner application.
7 Adjust the softpot value until the desired receive audio level is achieved at pin #7 (in reference to
ground) on the Aux connector Ground connections provided by the Aux connector are pins: 9,
16, 17, 18, and 19.

NOTICE: Optimally, it is recommended to load pin #7 with application loading used
during normal operation of the repeater.

Tx Audio Level Set
The procedure outlined in this section is used to allow adjustment of the transmitter audio level the
repeater is expecting at its Aux connector. Adjusting this level set has the effect of increasing or
decreasing RF signal deviation for a given transmit audio level. Perform this procedure any time the
transmitter audio level needs adjustment.
10.6.1
Tuning the Tx Audio Level Set
Procedure:
1 Connect the repeater’s transmitter antenna port to the Communication Analyzer.
2 Power the repeater from either an AC or DC source.
3 Apply a 1 kHz signal at the desired input level to pin #1 or #22 (in reference to ground) on the
Aux connector. Ground connections provided by the Aux connector are pins: 9, 16, 17, 18, and
19. See Figure 45: Auxiliary Connector on page 92.
